Air conditioning

Don’t run air-con all day – temperatures peak in the afternoon, so there’s no need to have air-con running first thing – especially if you ventilate the office overnight to reduce heat during hotter periods.

Keep it maintained – regular maintenance and scheduled services will save money in the long run. Make sure the coils, which eject heat from the system, are clean and exposed to fresh air.

Control it carefully – the trigger temperature should be higher than the thermostat’s heating, or you’ll end up paying for cooling and heating at the same time!

Consider alternatives– a simple desk fan is cheaper to operate than an air conditioning system, and could be a better option for smaller spaces.

Keep heat down – the hotter your office gets, the more work your air-con has to do. Using heat reflective materials like window films and paints can help here.
